Definetely worth it!! Even if you only get the health benefits it's still worth it. But think about it, what do you lose by becoming stronger, more enduring, and simply FEELING better? I'm not kidding anyone, I still have SP. But after a good workout or jog in the park, I simply feel great, and for the rest of the day it really makes a difference. I have noticed that in ALL cases, when I just get up last minute, stagger out of bed, and then go to work, I feel pretty dodgy. Try getting up 45 mins early, and going for a run. I guarantee you'll feel better for the rest of the day.
